“Sharp stones are under him: he spreadeth sharp pointed things upon the mire.”
Job 41:30 (KJV)
Context Reading
28The arrow cannot make him flee: slingstones are turned with him into stubble. 29Darts are counted as stubble: he laugheth at the shaking of a spear. 30Sharp stones are under him: he spreadeth sharp pointed things upon the mire. 31He maketh the deep to boil like a pot: he maketh the sea like a pot of ointment. 32He maketh a path to shine after him; one would think the deep to be hoary.
